Uninstall Oracle Java using the Terminal

It includes tools for developing, debugging, and monitoring Java applications. Oracle strongly suggests to now use the term JDK to refer to the Java SE Development Kit. The Java EE SDK is available with or without the JDK, by which they specifically mean the Java SE 7 JDK. Follow below steps to install JDK on Mac OS High Sierra 10.

Note: To uninstall Java, you must have Administrator privileges and execute the remove command either as root or by using the sudo tool.

Remove one directory and one file (a symlink), as follows:

  1. Click on the Finder icon located in your dock
  2. Click on Go in the Finder menu
  3. Click on Utilities
  4. Double-click on the Terminal icon
  5. In the Terminal window Copy and Paste the commands below:
    sudo rm -fr /Library/Internet Plug-Ins/JavaAppletPlugin.plugin
    sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane
    sudo rm -fr ~/Library/Application Support/Oracle/Java
Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
Note: After successfully uninstalling Java, you may remove Java Deployment cache using these instructions.
Can I restore Apple Java 6 after uninstalling Oracle Java?

Yes, see the instructions on the Apple website Restore Apple Java 6. If you have JDK 7 or later versions installed on your system and you want to restore Apple Java 6, then those JDK versions need to be uninstalled first. See the instructions to Uninstall JDK.
